5. “A good data warehousing professional is always scouting for new sources of data that can be applied to business intelligence … Plus, analysis can be richer and more open ended if you work with original XML documents, the same way you’d work with any detailed source data”.
In this spirit and to enhance an understanding of XML, develop an XML Schema based on the data warehouse data that a cube may capture and apply it to develop an XML document. (18 marks)
6. Implement a part of your source database or data warehouse as graph database using Neo4j technologies. Discuss the use of graph databases in comparison to relational databases. (15 marks)
